CLUTCH.

Application filed A5111 2} Be itlmown that I, Janus ToLLEs, a

citizen of the United States, residingat mechanism being portions being: indicated Dlauiondale, county o't Eaton; State of .hflichigan. have inventedflcertain new and useful improvements in Clutches, ot which the following is a specification.

This invention relates to improvements n clntchesl It relates more particularly to an improvement inclutches for clutching a H loose pulley on a shaft;

The object oi. the invention is to provide a simple and effective means which does not require the severing of the shaft' Objects relating to details and economies of construction and operation will. definitely appear from the detailed description to follow.

I a.c:.-on1plish the objects ofmy invention by the devices. and means described in the following! specification. The invention is clearly defined and pointed out in the claims.

."l. structure containing a preferred embodin'ient of my in vention is fully illustrated in the accompanying" drawing, forming a pa rt of this specification, in which:

Fig. I is a detaillongitudinal sectional View through a clutch and loose pulley structure embodying the features of my in'ven-' tion, the pulley and portions of the clutchshown. in section and other in full lines, the clutch being in disengaged position.

Fig. II is a similarview, portions being in section, showingthe clutch inoperation and being thrown into engagement .Tn the drawing similar numerals of reference refer to similar parts throughoutthe several views.

Considering the numbered parts of the drawing, 1 is the shaft, 2 is a loose pulley, counterbored at 3 and 4 at each end to form suitable projectingflanges and recesses for the clutch cngagingmeniber, and forming a central plain web 5, as appears from Fig. I. 6 is the clutch hub or support, which is secured to the shaft by setscrew 7. It has an extended flange 8 fitting: into the recessed. end 3 oithe pulley 2. somewhat enlarged journal 9 is t'orniedat the center for supporting the loose pulley the same being slightly reducedat 10 to receive the clutch member l-l, ,he 'reduced portion 10 being screw threaded at ll to receive the cylindrical block 12 which is screw threaded to fit the lateral support.

upoiuthe same and form for the clutchnieinber 14. The clutch bores 21 24: is forced into the 1921-, Serial no. 452,069.:

her 14: is supportedin counterbo'ret in Suitablewaslr fiber are interthe end of the loose pulley 2.- ers 15 which maybe of wood posed between the flange 8 and the pulley5 at one end', and the clutch inember ld and p the 'pulley5at the opposite end. dosed parallel to the are olung'ers 16 in suitable block 12; The plungers '16 have heads conical in for1n ,and are heldnorinally out otengagement by coil springs 19 disposed i n 'counterhored enlargements 20, soinewhat after the fashion of "Window stops. lugs 20." are provided to enable the ready introduction of these .plungers. Y f. Radial plungers 21 are disposed in radial and are provided with conical 22 which contact and coact with the 17 of the plunger-s, as clearly heads conical. heads appears in the figures. Screw plugs 23 are provided at the'outerends of these radial) plunger-s to permit their readyintroduction into the transverse bores. "Supporte(l on the shaft 1 is a clutch actuatingfmember 24%, which is sleevedand splined thereon and adapted to reciprocate back andv in the block L. The actuatingend of this clutch plugor member 2% is beveled at '25. The inner ends of the and project within the 13 so that they are readily acted upon by the member 245. The member 24 is provided witlrtlanges' 26, '26 which form a. suitable groove to receive the usual clutch actuating collar or fork, not shown. i I i i From this description I believeuthe operation of myimproved clutch will be very readily understood. The actuating member bore 13 and forces the which, due to their taperperipheryof the bore plugs 21.- outward lng heads, engage thetapering' heads ofthe plungers l6 and force the. same OutWaIdlY nto engagement with the clutch member 14. as seen in. Fig. II. The clutch member 14. rests loosely upon the shaft .untilit is clamped by the plunger 16. The structure is adjusted for wear, and also to secure the 7 best results by adjusting the block 12.011 the screw thread 11.

have described my improved clutch in its-preferred t'orin. bnt'desire to state that am aware it can be very considerably modified without departing from my invention. The clutch axis offthe shaft 3 bores 18 insaid Screw forth within the enlarged bore 13 plugs 21 are rounded necessary here to be actuating device is of special consequence and different clutch members though the simple disc and flanges that disc disposed on 'bore, spring plungers ters Patent 1s member with a calheads disposed so that their kinds and styles of nnght be employed, al-

have shown are entirely sufi ici'ent for. the purpose.

Having I claim as new and desire to secure by thus described my invention what I ers outwardly Letactuating plungers,

her with a tapered end disposed to enter said central boreior forcing the said radial plunto carry the spring plungers against the clutch disk, coacting for the purpose specified.

' 2. A clutch actuating member comprising a block adapted to be secured to a shaft having an enlarged central axial bore and smaller parallel bores, clutch actuating plungers disposed in the said smaller parallel bores with conical headsgradial bores an' radial plungers with conical heads disposed in said bores to coactwith the said clutc and a tapered member to force the said radial plungers outwar coacting as specified, Y

in witness whereof, I have hereunto set my hand and seal n the presence of two witnesses. Y Y JAlllES M TOLLES. \jL. s]
